wpa_cli: connect 3 device in a p2p group with WiFi Direct

Ok thank u for the answer and sorry for my delay.
Yeah, good point. 

I solved the problem, and i want to explain how for other people:
-After the connection between two devices i executed this command on device 1 (GO):
wpa_cli -iP2P_GROUP_INTERFACE_CREATED_BEFORE -p"socket_folder"
In this interactive instance of wpa_cli i used "wps_pbc". Now i'm sure that wps_pbc is running on the correct interface.

After that on device 3 i executed "p2p_connect device1address pbc join"
And all three devices are connected. 

Ok, now is working, but it's probably a GOOD IDEA to add a parameter to the command "wps_pbc" in wpa_cli to specify the interface. I lost one entire month for this thing.

Only one small question, not really necessary now, but i'm really curious: how can i pass this command "IFNAME=p2p-wlan0-0 WPS_PBC" in wpa_cli? I should use raw... or driver...? I don't understand.

You need to send that command to the correct interface, i.e., the group
interface (which could be something like p2p-wlan0-0) instead of the
global control interface or the main station interface. In other words,
that command is correct, but I'd assume you are issuing it to an
incorrect destination. I do not know how exactly the control interfaces
are configured to be used on the device you use, so I cannot provide the
exact command line that would need to be used. You could try something
like "IFNAME=p2p-wlan0-0 WPS_PBC" on the global control interface (and
replacing that "p2p-wlan0-0" part with the group interface name from the
